U0126-EtOH 生物活性

靶点	MEK2 MEK2, IC50:0.06 μM MEK1 MEK1, IC50:0.07 μM
描述	MEKs, which are members of the MAPKK family, can activate both ERK1 and ERK2 by catalyzing the phosphorylation on T202/Y204. Also MEK itself can be phosphorylated and activated through Ras when the upstream signaling is activated by extracellular stimuli, including growth factors, hormones etc.. U0126 is a selective MEK1/2 inhibitor with IC50 value of 70/60nM, but not ERK or Raf^[1]^[2]. Co-treatment with U0126 for 15min at concentration ranging in 1nM-10μM caused inhibition of PMA-induced p-ERK, the target of MEK1/2 in a dose-dependent manner in COS-7 cells. An in vitro study showed that U0126 represented much more potency to both wild type and ΔN3-S218E/S222D MEK compared with the another MEK1/2 inhibitor, PD98059^[2]. An in vivo study showed that U0126 is brain-permeable. Intravenous injection with U0126 at dose of 100mg/kg could reduce p-ERK1/2 in hippocampus after 10 min of reperfusion after 3.5 min bilateral carotid artery occlusion in male gerbils. Intravenous administration of U0126 at dose of 100-200mg/kg showed protective effect on the hippocampus against forebrain ischemia in male gerbils. Moreover, treatment with U0126 at 3 hours post ischemia significantly reduced volume after transient focal cerebral ischemia, accompanied with reduced p-ERK in the damaged brain areas^[3]. Also, it has been reported that U0126 helped maintain human pluripotent stem cells^[4].
作用机制	U0126 is a non-competitive inhibitor of MEK1/2, which can bind a common or two overlapping sites on MEK.^[2]
